Jump Gates are the core technology that allowed the Roman Empire to expand its influence across the galaxy.

These structures are hyperspace transit gateways, essential infrastructure for deep space navigation. Through them, Rome was able to efficiently develop vast colonial planets, rapidly transport resources, and deploy military forces across its territories. Each Jump Gate is strategically placed in orbit around the primary habitable planet of a colonized star system, ensuring both ease of access and control over interstellar traffic.

Hyperspace travel through Jump Gates requires at least two gates. In other words, both a departure and an arrival gate must exist for travel to occur, and this is crucial for round-trip navigation. A single gate would allow a ship to jump to its destination, but it would have no way to return, effectively making the jump one-way. This is why the Roman Empire always constructs Jump Gates in pairs or network clusters, ensuring stable two-way traffic between star systems.

Each Jump Gate is operated from a dedicated control chamber located on-site. This chamber maintains the stability of the gate through a local network and ensures that only authorized ships can pass. Operations are carried out by administrators and technicians stationed at the gate, and the Empire enforces a rotation system to prevent them from colluding with local powers. In addition, unannounced inspections are conducted to strictly monitor and control gate operations.

The original concept of the Jump Gate was designed by Greek scholars studying the Codex. The Roman Empire took their blueprints and, through massive investments of manpower and resources over many years, expanded the Jump Gate network across the entire Empire.

Today, Jump Gates are one of the most critical infrastructures supporting Roman interstellar civilization. All ships using the network must pay a toll, and the fee is substantial. With countless vessels passing through the gates every day, this toll has become a major source of revenue for the Empire.
